My Father lost his good job during the great depression and he hit the bottle, became useless as a Father. Could not support his family, could not hold a job, and finally my Mother left him with 5 kids to raise all by herself. I still don't know how she did it, but I do know she was tougher than a bag of hammers. While he was on one of his frequent drunks she sold the house and moved to another. She worked in a sardine factory, and as a domestic. We were dirt poor but we no longer had to tolerate his addiction and neglect.
He was not abusive, he was addicted to alcohol; he never knew where his next drink was coming from, and that was his only concern.

You can get by on your own if you have the courage. Alanon is a great support group, but you will find the solution inside yourself, not "out there" somewhere.
